Difflock engagement....reverse ?

Post#1 » Mon Sep 01, 2008 12:53 am

Curious, can difflocks be engaged in reverse ? Never tried it, never had or anticipate a need and never read any inquiry on such.

Just from my latest experience. I got stuck in the mud and pulled up on my rear diff lock and put the truck into reverse and they didnt engage, and now when i try to put my rear diff lock on I get a terrible grinding noise and it never engages... :?: :cry:

Any thoughts? Does this relate to engaging it in reverse?

Mike, I think the mechanism is designed to work in either direction, the engagement dogs are symetrical. Also I think you want to be able to back out of a situation that requires it. Shouldn't be a problem. The tractors I use have this capability and it works in revers too.

Thanks Dai. Snyder you may have other issues causing your grinding like sticky cylinders, sounds like you are not getting "full engagement" of the locking mechanism. I am not an expert on the subject, so a little hard to diagnose. You may want to start a thread to ask for help/input on solving that problem.

I'm no expert on difflocks ( Harald is supposed to be writing a book about them! Maybe he'll chime in) but it seems the common wisdom is to always engage them before coming to an obstacle that may get you stuck. They need some distance to engage. When you are already stuck and loose traction on one wheel it is possible to have that wheel spinning very fast when you try to engage. I believe this is when damage can occur. You want to engage them while moving slowly.

I'll look for some of Haralds posts on this subject. It has been discussed extensively.

Hate to hijack a post, but I went to a little spot up the road and got the truck to engage the rear locker BEFORE getting almost stuck... and viola! it works again. I do think that the front diff lock needs a new master cylinder, it wont move at all. I'm not sure why it wasn't engaging at all the other day, I did pull on the level yesterday while I was moving very slowly and my diff lock light did light up again.

Snyder, I had "lazy" difflocks that were slow to disengage last year when I went on an adventure with Harald and others. It took a full day of off-road before disengagement.
When I got home I tried flushing and had problems getting fluid to come out the rear locker cylinder, which was a big clue I had problems in the master cylinder hydraulic line area. I took out the master cylinders and found corrosion inside. A rebuild kit was in order and now all is well at the push/pull of the difflock knob.
